Specification of Letters Patent.

Application filed October 2, 1913. Serial No. 792,947.

To all whom it may concern:

Be it known that I, GEORGE E. PRENTIGE, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Binders for Cord Ends, of which the following is a specification.

My invention relates to improvements in binders for cord ends, and the object of my improvement is to produce a binder for button cord loops and cord ends for suspenders that can be used for binding a button cord to either a single or a double cord end and the object of my improvement is simplicity and economy in construction and convenience and efliciency in use.

In the accompanying drawing Figure l is a front elevation of my improved binder for button loop and cord ends as used to secure a button loop'to a single cord end.

Fig. 2 is a similar view of the same as used with a double cord end.

Fig. 3 is a rear elevation of the parts shown in Fig. 1.

Fig. 4 is a rear elevation of the parts shown in Fig. 2. I

Fig. 5 is a plan view of the blank for the same.

Fig. 6 is a sectional view on an enlarged scale on the line a: m of Fig. 1.

Fig. 7 is a similar view on theline 3 3 of Fig. 1.

Fig. 8 is a similar view on the line a a of Fig. 1.

Fig. 9 is a side elevation of the binder as bent up previously to assembly.

My binder for loops and cord ends C01T1- prises a piece of sheet metal of generally rectangular formation in the blank as shown in Fig. 5 and having a set of teeth or prongs 10 along the lateral edges.

The blank as shown is bent into U shape and along the longitudinal axis is provided with a set of corrugations 11 along the front Wall 12 as shown in Fig. 9.

The corrugations 11 extend entirely across the said front wall 12 and are suiticient in number so that a plurality will engage with each of .the cord ends inserted from the ends inwardly and each entering to about the middle of the length of the binder.

The side walls 15 as shown in the said Fig. 9 are plane and have the teeth 10 mentioned along the free lateral edges.

The cord ends inserted as described comprise in each case the ends 14 of the button loop 16 at one end and at the other end the main cord generally larger and of a material having a different character from the cord or thickness being such as to permit of appreciable distortion in each case. No dis tinction is made in the method of assembly or manner of operation or in the appearance of the finished connection, so far as the binder is concerned between the connection of a single cord end, such as 13, or double cord ends, such as 17 or 14;. The cord end or ends, asthe case may be, have the opposed tip ends in abutment, as shown in Fig. 6, there being no overlapping of the two cord end portions that are connected to the corresponding end portions of the binder, so that one end portion, or essentially one half of the binder is connected to one cord or cord group, and the other half to the other cord group, each group being connected to, the binder,independently of the other.

It is understoodthat changes in the dimensions may be made to accommodate cords of different dimensions.

After the cord ends have been. inserted in I the binder the latter is closed over the same under pressure by having the lateral ends closed over inwardly and the teeth 10 are embedded in the body of the cord in each case. In the closing operation described the lateral. edges of the side walls 15 are brought into abutment and are forced inwardly against the body of the cord in the case of the single cord 13 and the teeth 10 provided thereon are forced into the same and in the case of the double cord 14 and 17, the edges are brought between the cords and the teeth 10 maybe embedded in the cords due to the combined effect of the curved formation of the same resulting from the curling feature of the closing operation and to the fact that the cords ends are appreciably de formed resulting from the heavy applied pressure.

I find in fact that the precise form of the teeth 10 is not important and in fact they may be dispensed with entirely as the corrugations 11 effect all the holding that is necessary under ordinary conditions.

Where the teeth are provided however, I prefer to have them in staggered relation as shown. It will be noted that an even number of teeth 10 is shown along one edge and an odd number along the other, and these are in staggered relation, as mentioned.

The result of lniving the teeth 10 staggered is to produce a longitudinal corrugated effect of the cord which combined with the cross-wise corritigations 11 produces a hold ing effect that is especially effective and reliabld.

It will be noted that the corrugations 11 are relatively large, and correspondingly few in number and they are defined by V-shaped indentations in the form of ribs extending across the front face of the binder, as shown in the blank in Fig. 9 and in the sectional view in Fig. 6. These produce a similar form for the material of the cord ends, and have a superior holding effect as compared with that of a greater number of smaller corrugations.

Furthermore, the teeth 10, because of their being curled over in the assembly operation are positioned to one side of the central plane, as shown in Figs. 7 and 8, so that they are positioned in staggered relation in the cord ends.

That is to say that the teeth 10, owing to the combined effect of the staggered arrangement in the blank and the peculiar curling effect produced in the teeth by the assembly operation, are arranged in off-set relation alternatively in the body of the cord ends that are inclosed by the binder.

In explanation of how this condition is effected it will be noted that the binder, in condition for use, as shown in Fig. 9, is of U shape, and as mentioned, the side walls 15 are plane, and the teeth 10 are extended from the edges of the side walls 15 and in the same plane.

In the assembly operation, dies are used comprising for the lower die a formation suitable to support the front wall, with the corrugations 11, and for the upper die a curved or arched wall which first engages with the teeth 10, curlingthe same and closing them inwardly, and following along the teeth as mentioned they impart a curved formation to the entire side wall 15 to form curved side and rear walls of the assembled binder. The edges of the binder are in abutment, and are turned inwardly, and effeet a longitudinal corrugation of the cord and binder. This longitudinal corrugated effect is at tie rear side of the binder and is opposed to the cross-wise or transverse corrugated effect at the front wall due to the corrugations 11. This combination in itself affords a particularly eliicient holding or binding effect, so much so that the teeth 10 may in some cases be dispensed with, as has already been mentioned.

Where the teeth 10 are used, these, owing to the initial engagement with the upper die as described, are curved relatively to the adjacent side wall 15 so that in the position after assembly they are directed outwardly, toward the sidewalls, and in each case to ward the particularside wall with which it is connected, and outward from the longitudinal corrugation, corresponding to the edge with, which it is connected.

That is to say, notwithstanding the factthat the teeth are connected to edges that are positioned along the center, or in a longitudinal plane, the ends and body portions of the teeth are directed outwardly from the said plane.

FtlltllbllllOlQ, owing to the fact that the teeth are arrangedalternatively on opposite sides of the said plane, the holding effect of the said teeth is equivalent to a third corrugated effect, the cord being compressed into a winding or serpentine formation within the binder.

I claim as my invention 1. A binder and cord end combination comprising a binder of generally tubular form and cords having their ends entered within the two end portionsthereof, the said cords being of appreciable thickness and having a circular form of cross-section, the front wall of the said binder having a plurality of transversely extending and rearwardly directed V-shaped ribs embedded in the said cord ends, having atthe rear opposed and.longitudinally extendingedges which areadjacent and embedded forwardly into the material of the said cord ends so as to form a relatively large and generally if-shaped longitudinal corrugation, a phirality of teeth on each of the said edges, the said teeth being curled over and directed generally outwardly relatively to the said longitudinally extending edges and embedded in the material of the said cord ends, and the said teeth on one edge being in alternate relation to the teeth on the other edge, whereby the said teeth will effect a wavy distortion of the material of the said cord ends.

2. A binder and cord end combination comprising a. binder of sheet material bent into generally tubular form and cords ha ving their ends'extending Within the said binder, the said cords being of appreciable thickness and having a circular form of cross-section, and the said binder being so formed as to effect a connection with the said cord ends by a distortion of the material of the said cord ends from the front rearwardly, from the rear forwardly, and from the middle of the rear generally laterally and outwardly comprising transversely extending V-shaped indentations in the front wall, opposed longitudinally directed edge portions at the rear directed forwardly in approximately V-shape, and teeth on the said opposed edges that are directed laterally and outwardly relatively thereto.

3. A binder and cord end connection comprising a binder of sheet material and a cord end connected thereto by aconnection involving a distortion of the material of the said cord end within the said binder in three general directions, consisting of a plurality of transverse rib-like formations on the front face, a longitudinally extending V- shaped corrugation at the rear face, and an internal, wave-like relative displacement of the material whereby different parts of the said material are forced away from the central longitudinal line and toward opposite sides.
